Reusing Gyroscope - salvaged from old camera

enessoylutr
enessoylutr over 4 years ago

Hello, I am new in the community. Hope this is the right place for this question. I disassembled a camera and in one of the circuits there are two accelometers perpendicular to each other. I just want to learn how can I read and understand data from it. But I couldn't understand the circuitry. Could someone give me some pointers in that? I only have a multimeter as a testing device, by the way. Please find attached image.image

    Hi Enes, With any part, you need to examine the datasheet, it will describe what you're requesting. You need to find the datasheet for the part (e.g. via google. Or if you somehow have the circuit diagram…

    Welcome to the E14 community. Your inquisitiveness will stand you in good here. It may also be a curse when the answers you seek are not forth coming. I would tend to agree with shabaz and see a more efficient…

    Thanks a lot for the replies. Unfortunately, I can't find any datasheet nor a useful info from cameras specifications. Only it has image stabilisation, perhaps that's why there is a gyro in it. Powering the device and then inspecting what's going on would be a good option but it is no longer able to operate image.

     

    I could buy an accelerometer kit but I am more interested in reusing these tiny components. After searching about how accelerometer work and finding out the MEMS, I was under the impression that it should just give arbitrary capacitance depending on the angle.

    So then, I can somehow map the output capacitance to the angle, but don't know how to measure capacitance from this components image

     

    Maybe I can go ahead and buy a kit and then observe it, as you guys suggested.

    MEMS accelerometers almost always have signal processing on board because processing the signals from the tiny capcitance of the sensors is much too difficult and expensive off chip.

    Have a look at ST and Analogue Devices websistes to get an idea of what real life accelerometers look like.

     

    I don't recognize the manufactuer ID on the parts in your picture.

     

    How many pins do they have, and when was the phone made.

    No idea honestly, camera should not be that old, and there are 4 pins for each, I am guessing.
